Fiber–fiber interactions in carbon mat thermoplastics
Carbon mat thermoplastics (CMT) consisting of 12.7 mm long, chopped carbon fibers in a polypropylene matrix were manufactured using the wetlay technique at fiber volume fractions (FVF) from 10% to 25%, and tests simulating the compression molding process were conducted. The packing stress of the CMT followed a power law relation with FVF. A single fiber pull-out fixture was used to measure the ...
متن کاملDesigning of the Heating Process for Fiber- Reinforced Thermoplastics with Middle-Wave Infrared Radiators
Manufacturing components of fiber-reinforced thermoplastics requires three steps: heating the matrix, forming and consolidation of the composite and terminal cooling the matrix. For the heating process a pre-determined temperature distribution through the layers and the thickness of the pre-consolidated sheets is recommended to enable forming mechanism. Thus, a design for the heating process fo...
متن کاملFiber-reinforced tough hydrogels
Using strong fibers to reinforce a hydrogel is highly desirable but difficult. Such a composite would combine the attributes of a solid that provides strength and a liquid that transports matter. Most hydrogels, however, are brittle, allowing the fibers to cut through the hydrogel when the composite is loaded. Here we circumvent this problem by using a recently developed tough hydrogel. We fabr...

متن کاملFiber Reinforcement Induced Warpage on Injection Molded Thermoplastics
1 Abstract The warpage characterizations of injection molded plastic parts are not standardized and very challenging due to its complex process. This paper presents a novel examination method of the deformation of injection molded plastic parts especially for fiber reinforced materials. A special, but simple part was introduced for the description of the effect of different technological parame...
