matrices

What is the main role of a matrix in a composite material?

• To increase the density of the material

• To bind fibers together and transfer stress

• To act as a reinforcement material

• To reduce the overall cost of production

Which of the following is a characteristic of thermoset matrices?

• They can be reheated and reshaped multiple times

• They require heat or a catalyst to cure and cannot be remelted

• They are always biodegradable

• They have lower mechanical strength than thermoplastics

What is the key difference between thermoset and thermoplastic matrices?

• Thermosets can be reshaped by heating, while thermoplastics cannot

• Thermosets are soft at room temperature, while thermoplastics are rigid

• Thermoplastics can be reheated and reshaped, while thermosets cannot

• Thermosets have lower mechanical strength than thermoplastics

What is one advantage of bio-based matrices over petrochemical-based matrices?

• They generate 68% more greenhouse gases

• They require more energy to produce

• They are completely renewable and environmentally friendly

• They cannot be recycled

Which factor significantly affects the performance of an advanced biocomposite?

• Fiber orientation

• Electrical conductivity

• Color of the matrix

• Amount of air in the composite
